Abstract
The utility model discloses an electrical switchgear pressure release structure, its key lies in: electrical switchgear pressure release structure is including setting up in the pressure release cover at cubical switchboard top, and bolt and cubical switchboard top edge connection are passed through to four angles of this pressure release cover, and the pot head is equipped with compression spring and final and fixes with the nut under this bolt to it separates certain distance to make between nut and the cubical switchboard top, the pressure release cover still is provided with the pressure release hole all around. The pressure release cover still is provided with the pressure release hole all around, and be provided with between the marginal top surface in the bottom surface and cubical switchboard top of pressure release flaring reason and slowly fall the device, the utility model discloses simple structure, convenient to use can ensure that the inside pressure energy of cubical switchboard obtains release very fast, has thoroughly avoided the danger of cubical switchboard explosion, has reduced economic loss.
Description
Technical field
This utility model relates to a kind of cabinet pressure relief.
Background technology
Switch cubicle is a kind of large electric appliances equipment, has substantial amounts of electronic component, operationally can produce substantial amounts of heat inside it；When normally working, these heats can be come out by the louvre on switch cabinet body.But, once inside switch cabinet element failure, will produce substantial amounts of heat and pressure, the louvre on switch cabinet body cannot quickly discharge the energy within cabinet, it is possible to the danger causing switch cubicle to explode, brings huge potential safety hazard and economic loss.
Utility model content
The purpose of this utility model is to provide a kind of cabinet pressure relief.
To achieve these goals, by the following technical solutions, a kind of cabinet pressure relief, it is characterized in that: described cabinet pressure relief includes being arranged at the pressure release cover at switch cubicle top, four angles of this pressure release cover are connected with switch cubicle top by bolt, this bolt lower end is arranged with compression spring and finally fixes with nut, so that separated by a distance between nut and switch cubicle top；Described pressure release cover surrounding is additionally provided with relief hole, it is provided with slow descending device between the bottom surface of pressure release shroud rim and switch cubicle top end face, wherein slow descending device by fix cylinder and be positioned at fixing cylinder slide movable post form, the sloping platform that the inwall of fixing cylinder is provided with in inclination, the surface configuration of movable post has the reed of level.
A length of more than the 10CM of described compression spring.
This utility model simple in construction, easy to use, by arranging, at switch cubicle top, the problem that pressure release cover solves inside switch cabinet pressure release；When equipment normally works, the relief hole of pressure release cover surrounding can help inside switch cabinet ventilation and heat, reduces the internal probability broken down；Break down once switch cubicle and produce huge energy and pressure, internal pressure can upwards jack-up pressure release cover, owing to being provided with compression spring on the pressure release cover connecting bolt with switch cubicle, therefore, pressure release cover can be opened by jack-up, so that it is guaranteed that the pressure of inside switch cabinet can quickly be released, thoroughly avoid the danger of switch cubicle blast, decrease economic loss.

Detailed description of the invention
With specific embodiment, this utility model is described further below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, a kind of cabinet pressure relief, described cabinet pressure relief includes the pressure release cover 2 being arranged at switch cubicle 1 top, four angles of this pressure release cover 2 are connected with switch cubicle 1 top by bolt 4, this bolt 4 lower end is arranged with compression spring 5 and finally fixes with nut 6, so that separated by a distance between nut 6 and switch cubicle 1 top；Described pressure release cover 2 surrounding is additionally provided with relief hole 3, it is provided with slow descending device between the bottom surface of pressure release shroud rim and switch cubicle top end face, wherein slow descending device by fix a 7-2 and be positioned at fixing cylinder slide movable post 7-1 form, the sloping platform 7-3 that the inwall of fixing cylinder is provided with in inclination, the surface configuration of movable post has the reed of level.
A length of more than the 10CM of described compression spring 5.
This utility model simple in construction, easy to use, by arranging, at switch cubicle top, the problem that pressure release cover solves inside switch cabinet pressure release；When equipment normally works, the relief hole of pressure release cover surrounding can help inside switch cabinet ventilation and heat, reduces the internal probability broken down；Break down once switch cubicle and produce huge energy and pressure, internal pressure can upwards jack-up pressure release cover, owing to being provided with compression spring on the pressure release cover connecting bolt with switch cubicle, therefore, pressure release cover can be opened by jack-up, so that it is guaranteed that the pressure of inside switch cabinet can quickly be released, thoroughly avoid the danger of switch cubicle blast, decrease economic loss.The sloping platform that the inwall of fixing cylinder is provided with in inclination, the surface configuration of movable post has the reed of level.Such design, so that the process that pressure release covers on decline is slow, extends the time that pressure release cover declines, it is to avoid the short time repeatedly explodes the impact to pressure release cover.
Claims (2)
1. a cabinet pressure relief, it is characterized in that: described cabinet pressure relief includes being arranged at the pressure release cover at switch cubicle top, four angles of this pressure release cover are connected with switch cubicle top by bolt, this bolt lower end is arranged with compression spring and finally fixes with nut, so that separated by a distance between nut and switch cubicle top；Described pressure release cover surrounding is additionally provided with relief hole, it is provided with slow descending device between the bottom surface of pressure release shroud rim and switch cubicle top end face, wherein slow descending device by fix cylinder and be positioned at fixing cylinder slide movable post form, the sloping platform that the inwall of fixing cylinder is provided with in inclination, the surface configuration of movable post has the reed of level.
2. cabinet pressure relief as claimed in claim 1, it is characterised in that: a length of more than the 10CM of described compression spring.
